expiry of the timeout a discard callback removes undelivered PDUs
from the queue.
- Added the mechanisms to the notify_delivery to remove PDUs from the
undelivered queue when the PDU is ACK'ed.

Fix race condition in rlc_am_stress test and other fixes related to this
...
test. The race condition was being cause by write_sdu being called
simultanously to read_pdu, which could cause the read_pdu to try to get
the SDU info before it had been written by the write_sdu.
Changes in this commit include:
- Make sure PDCP sn in included in RLC AM stress test.
- Stop handling control PDU when TX is not enabled in RLC AM.
- Fixed issue with length of the PDCP SN in rlc_stress_test.
- Moved the place were sdu info erase was called to avoid double calls to erase
- Tentative fix for race condition in rlc_am_stress test.
- Added function to print information about undelivered_sdu_info_queue
for debugging.

Added the ability of the RLC AM to notify the PDCP of the acknowledged
...
PDCP PDUs. This includes:
- Modifying the byte_buffer_t to include PDCP SN meta-data. This way,
the RLC can keep track of the ack'ed bytes for a specific PDCP PDU.
- Added in the RLC an `undelivered_sdu_info queue`, to keep track of the
amount of ack'ed bytes and the total size of the PDCP PDU,
so the RLC can know when delivery is finished.
- Added an interface between the PDCP and the RLC so that the RLC can
notify the PDCP when it receives an ack from the status PDUs. The RLC
passes to the PDCP a vector of all the ack'ed pdus in a rx'ed status PDU.
- Added some tests to the notify functionality. This includes some tests
where the PDUs are acked imediatly, and one test where the PDU is
retx'ed.

mac_pcap: refactor MAC PCAP and include NR RAT into same object
...
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.
This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.

RLC TM can't be segmented so it may happen that a PDU

rf_imp: fix stopping of AGC thread

hard killing of AGC thread causes issue on some RF devices,
such as the N310. The thread still seemed to access the device while
the radio was already killed (or the streamer object deleted).
It's unclear why this isn't causing similar issues on B210 or X310,
at least not visible, but it is obviously not the correct way to stop a thread.
The patch now correctly sets the stop flag for the AGC thread, wakes it
it up and waits until it has terminated.

mac_pdu: reset subheader state when deleting from PDU
...
when packing MAC PDUs, adding a new SDU might fail, for example
because RLC couldn't provide a new PDU. The muxer then needs
to delete the subheader from the PDU again.
When adding a padding BSR at the end, the same subheader is again
used to store the BSR, so any state in that subheader should be removed.
In the particular case, this was causing an issue when logging a LBSR
because the LCG buffer states are printed using the payload buffer,
which was still pointing to some memory that was used when trying
to add the new RLC PDU in the beginning.

pdu: fix unpacking of LCG2 of LBSR MAC CE
...
LBSR packing is fine but this makes the eNB do wrong things
because it thinkgs LCG2 has no or too much data to send.
LCG2 is our default LCG for DRB1. One occasion we saw the issue
is doing full rate TCP DL which requires quite a bit of ACK traffic
back to the sender. With the BSR for LCG2 being wrong, providing
UL grants was delayed and so the TCP DL throuhgput was very low.
In the log below we see that the buff_size[2]=1 so there is data to send.
Interestingly, the packing was correct so Wireshark displays it correctly.
But the unpacking not, as can be seen in the MAC log below which reports
0 buffer state for all LCGs
22:08:54.804792 [MAC ] [I] [ 5084] pdu_get: sdu_len=1212, channel.sched_len=1213, bsr.buff_size[2]=1

rlc_am: fix poll bit during header reconstruction
...
this makes sure that the reconstructed RLC AM header
has the poll bit set when any of its segments had it set.
this triggered a bug in RLC AM because the Status PDU
isn't transmitted for a RLC PDU that was segmented and
only the first segment had the P flag set.

Remove unnecessary Lime calibration step from Soapy implementation
...
When using srsLTE with Lime devices, calibration was performed before any configuration steps have happened, thus making calibration values invalid. Removing Lime specific calibration step from rf_soapy_imp makes so that devices will be automatically calibrated by SoapyLMS on rf_soapy_start_stream call.
Tested and working with srsENB using LimeSDR-USB v1.4 and LimeSDR-Mini v1.2 boards.

libsrslte_rf.so.0 -> libsrslte_rf.so.20.04.2
libsrslte_rf.so -> libsrslte_rf.so.0

rlc: increase RLC Tx SDU queue
...
the Tx SDU has been set to 128 PDUs because this gives approx.
150kByte UL buffer state (max value for Rel 8 BSR).
Previously, however, we've always reported too much pending UL
data because we weren't subtracting the transmitted data from
the reported data.
with this newer BSR reporting, however, even with full buffers we would
never report full buffers because the queues size is too short.
This seems to cause issues for iperf TCP sessions not resulting
in full DL rate, see isse #1703 . It seems that the TCP bandwitdh
probing works better with larger buffers (in our case this can
only be achieved with more PDUs in the pool).
This should fix #1703

pdu: refactor MAC PDU class

this patch refactors the MAC PDU class, the main changes are:
* add to_string() method to pretty print PDU and subheaders
This allows to have a single log entry per MAC PDU with all its
contents.
It removes the C-style fprint() method
* Simplity payload vs. w_payload_ce
Before we've used payload when reading the PDU and w_payload_ce
as a buffer when writing. In all getters we needed to differentiate
between both. Now payload points to w_payload_ce initially and is
only updated when parsing a new PDU.
* add various helpers, e.g. to get subheader index, update a BSR, ..
